What does Chrome actually report in delta values?
Looks like that IE/Edge doesn't have this feature since Shift+wheel causes navigating history like us. Chrome just swaps default action (i.e., not touching DOM event values). I wonder, wheel related events are cancelable, that means that it does NOT represent default action's behavior. So, perhaps, we can just take the Chrome's behavior? (Even if web apps check their implementation only with Chrome, it won't cause any problem only on Firefox.) That's not ideal behavior from a point of view of DOM events, but low risk approach in the real world. FYI: At bug 1358017 Comment 2, similar issue on vertical writing web pages, dbaron thinks that only changing default action is reasonable.

Firefox is missing this very convenient page-navigation short-cut. Use Case: As my eyes age, I find myself always scaling up the web pages I read (by holding down crtl and scrolling my mouse wheel). Doing this, often makes the page exceed the width of my monitor (hiding the right-side of the text I want to read) and produces a horizontal scroll bar at the bottom of the page. At this point, since I've already used ctrl-scroll-mouse-wheel to magnify the page, it would be wonderful if I could use shift-scroll- mouse-wheel to horizontally-scroll the magnified page and therefore center the (previously cropped) text that I am wanting to read.
